Yes, the Fedora Emacs has this site-start

;;; loaded before user's ".emacs" file and default.el

;; load *.el and *.elc in /usr/share/emacs/site-lisp/site-start.d on startup
(mapc
 'load
 (delete-dups
  (mapcar 'file-name-sans-extension
          (directory-files
           "/usr/share/emacs/site-lisp/site-start.d" t "\\.elc?\\'"))))
(setq source-directory "/usr/share/emacs/24.5/")




and the Guix Emacs has

(require 'guix-emacs nil t)

This is the same for both Emacses

Face: variable-pitch (sample) (customize this face)

you were spot on on this ! In fact evaluating this line made the Guix Emacs
window exactly equal to the one of the Fedora Emacs !

Right ! Even the minibuffer now is reasonably large and readable !

I installed this adwaita thing but the icons keep not being there

Also the Fedora Emacs keeps being a bit brighter

But that's not that bad ! The showstopper was the tiny tiny minibuffer

And if that's a mistery to you, go figure what it is to me ;-)

Thanks for your help ;-)
